My 9mm ASA bolt is hit the hammer so violently that the hammer pin is working out of the receiver. I understand ramping the back of the bolt can fix this. Anyone have a source for the modification to the bolt?

Ar15 ramp and use as is, and, can use .223 hammer now no need for 9mm hammer. M16 ramp and get a rate reducer or a heavy buffer to help counteract ROF increase. (IF ROF increase [:D]is not welcomed)
